地球（Earth）的磁层或许并不能保护我们免受超级风暴的侵袭

一项新研究指出，数据分析中的回归均值效应可能导致我们严重低估了太阳风暴的潜在强度。这表明地球磁层在应对极端空间天气事件时的保护能力可能不如预期。

Science seems like a straightforward endeavour. You come up with a hypothesis, collect data to prove or disprove it, and analyze that data to see if the hypothesis is right. But anyone who actually does science will tell you many times it’s not that straightforward. And one of the most common complexities is in data analysis. A new paper suggests that one such complexity, known as regression to the mean, might be causing us to massively underestimate how severe solar storms can truly be.
